For a car, the normal oil temperature ranges between 70 to 90 degrees Celsius. Under high engine load conditions, it may reach 100 to 110 degrees Celsius. Functions of engine oil: 1. Reduce wear between the piston and cylinder, as well as between the main shaft and bearing bush, providing lubrication; 2. Assist in cooling the engine internally; 3. Clean carbon deposits, sludge, and metal wear particles from engine components; 4. Minimize gas leakage and prevent external contaminants from entering; 5. Absorb shock and reduce the load on pistons, piston rings, connecting rods, and crankshaft bearings; 6. Decrease frictional resistance, conserve energy consumption, and minimize wear.

How Long Can the Parking Air Conditioner Be Used?

There is no fixed usage time for the parking air conditioner, but it is not advisable to use it for too long. It is generally recommended to ventilate every 3 to 4 hours. Prolonged operation of the air conditioner will increase the load on the refrigeration system, which is not good for health. You can turn it off for a while and then turn it on again. Do not sleep in a closed car with the air conditioner on, as poor ventilation in the car may allow carbon monoxide from the engine to seep into the car, potentially causing carbon monoxide poisoning. Factors that affect the usage time of the parking air conditioner include: 1. Car battery capacity; 2. Air conditioner temperature setting; 3. External temperature; 4. Vehicle structure; 5. Vehicle airtightness; 6. Air conditioner power.

Can You Sleep in the Car with the Heater On?

You should not sleep in the car with the heater on. When the car's heater is running in recirculation mode, carbon monoxide emitted by the engine can enter the cabin through the air conditioning system. With the windows closed, the concentration of carbon monoxide inside the car can gradually increase, potentially leading to poisoning. 1. Types of car heaters: They can heat either the air inside the car or air drawn from outside, raising the interior temperature. Car heating systems come in various types, classified by heat source into hot water heating systems, gas heating systems, exhaust heating systems, etc. Currently, most passenger cars primarily use hot water heating systems. 2. Functions of car heaters: The car heating system provides warmth to the cabin. When there is a significant temperature difference between the inside and outside of the car, frost or fog may form on the windows, obstructing the driver's view and compromising driving safety. Activating the heating system can help remove frost and fog from the windows.
